To create a code block, you have two options. First is to use 3 backticks at the beginning and at the end
function myFunc() {
// do something
}
Or to use indentation of 4 spaces.
function myFunc() {
// do something
}
And that’s why it happens. That’s standard markdown, I am not sure if you’re able to disable it.
You should be able to view the Raw Code of this comment, I believe.
